* COFF linker: postpone import section generation until unreferenced sections (and imports) are removed, and put all remaining imports into a single section. This is much more efficient than generating multiple smart-linkable import sections and immediately discarding a good half of them.

- TObjData.sectiontype2options: removed oso_keep flags. They don't have any effect here because this function is used only during assembling, and oso_keep cannot be represented in object files and therefore gets lost before linking.

* Don't calculate data position of each object section. Instead, write out a copy of exesection's memory image, i.e. every objsection is placed at the same offset from its owning exesection both on disk and in memory. This approach is simpler and works regardless of alignment requirements, while existing one could work only if SectionDataAlign<=SectionMemAlign.

+ ELF linker. Works on x86_64-linux and i386-linux good enough to pass the testsuite, but still requires a lot of work in nearly all aspects. In particular, no attempt to resolve symbols from shared libs is done, everything is just treated as imports. Symbol versioning isn't supported either.
